' Application filed May 22 1926. Serial No. 111,003.

My present invention pertains to valves; and it contemplates the provision of a valve composed of but a few parts and so characterized that packing is not necessary to guard against leaking, and also so character ized that it is susceptible of easy manipulation and is adapted to last for an indefinite period of time with no repairs or other attention.

To the attainment of the foregoing, the invention consists in the improvement as hereinafter described and definitely claimed.

.In the accompanying 'drawings forming part of this specification:

Figure 1 is a view partly in longitudinal section and partly in elev'ation'of the valve constituting the preferred embodiment of my invention. I

Figure 2 is a full side elevation of the valve.

Figure 3 is a transverse section taken in the plane indicated by the line 33 of F are 2, looking toward the left.

Similar numerals of reference designate corresponding parts in all of the views of the drawings.

Among other elements my novel valve comprises a casing body 1, preferably equipped adjacent to its heel end with an enlargement 2 and with a threaded end portion 3. The said casing body 1 is provided with a bore 4: at the forward end of which is a seat 5, and immediately in frontof the said seat 5 the casing body 1 is provided with a lateral swell 6 in whichis a chamber 7 in communication with a lateral spout 8, which spout 8 is designed when the valve body 9 is in open position'to discharge water or other liquid from the bore 4 and the chamber 7.

In front of the chamber 9 and spout 8, the casing body 1 is provided with a cylinder portion 10 exteriorly threaded at 11 and having a bore 12 for the reception and rectilinear movement of the valve body 9. The

said valve body 9 is bevelled at its inner end as designated by 13 to correspond to the seat 5, and 1s provided at its end with a longitudinal slot 14 and it is also provided adjacent to its outer side with a reduced circular portion 15, beyond which it has a threaded end portion 16 in which there is a kerf 17 The threaded portion 16 is for the reception or engagement of a nut 18, the said nut being preferably of angular configuration and being adapted to be held against turning while the valve body 9 is turned into engagement with the nut through the medlum of a screw driver or other ap-:

propriate implement engaged with the kerf 17 At 19 is what I designate the combined nutand hand wheel of my novel valve, the

said combination device being provided with a knurled circumferential portion 20 and being also provided with an apertured end wall'21 and an interiorly threaded portion 22. The said end wall 21 is swivelled on the reduced circular portion 15 of the valve body 9, and the said interiorly threaded por tion receives the threaded portion of the casing body 1, after the manner shown in Figure 1. A screw 22 is threaded into the side of the cylindrical portion 10 of the casing body 1 and is provided with a reduced inner por tion 23, disposed in the groove or slot 14 of the valve body 9. By virtue of the cooperation of the slot 1 1 and screw 22, the valve body 9 is held against any movement save rectilinear movement, and outward or opening movement of the valve body 9 is limited with the result that there is no liability of the valve body 9 and its appurtenances being casually detached from the casing body 1.

It will be appreciated from the foregoing that the element 19 of my improvement is disposed at, the forward end of the valve where it is convenient of access and is adapted to afford means for the easy and quick manipulation of the valve. It will also be appreciated that rotation of the element 19 in one direction will be attended by rectilinear outward movement of the valve body 9, while rotation of the element 19 in the opposite direction will bring about inward rectilinear movement and tight closing of the valve body 9 against the seat 5, and this in such manner that leakage is preeluded notwithstanding no packing is employed,

It will further be appreciated from the foregoing that my novel valve is extremely simple and inexpensive in construction and is entirely free of delicate parts such as are likely to be worn out after a short period of use.

The novel valve is further advantageous because of the simplicity and compactness of its structure, and also because of its adaptability to be embellished so as to eni a i hance rather than detract from apparatus with which it may be associated.

I have explicitly des c 'ibe cl the preferred embodiment of my irwenuoniii order to" impart an understanding of said embod i ment in all of-its details. I do not desii however, to be understogdas self to the precise construction disclosed, my invention being defined by, my: append-- ed claim? within tlief scope: of which modififi r tionslnay be made without'depal'tulfe from rhyi invention.

Having described my invention, what claim and desire" to. seizure by IlttElIS- In a valve andincomhinatiome casing videdjwith an exterior tl'pread; afHfejctllihear- 1y movable valve body circular in cross section and of even diarneter throughout its lngfth diptised in tlib bore in the forward p ortionof the casing body and having its inner end beveled and opposed to said Valve seat andalso, having; a longitudinal slot in its side and further having a circular reducedportion adj cent to its forward end and a further reduced and threaded forward end; an inwardly; projecting portion carried-. by the casi i'gbody and disposed in the slot of the vulgve body, a coinbiued'nut and hand wheel interiorly threaded and engaging theforward exterior tlirexac l of the casing body and haying, an end Wall in which is a central circular aperture snugly. receiv ng the circular reduced portion; of 1 l t e valve body, an fliet av 3 knurledcircumferential portion, and a nut mounted on the thjreadedend-portion of the valve body and opposed'to the said end Wall of the combined nut and hand Wheel.

In testimony whereof I afiix my signa- WERNER BAUMGARTNER.
